Fig. 2From: Metabolic engineering of Corynebacterium glutamicum for producing branched chain amino acidsa Schematic illustration of lrp-PbrnFE biosensor responding to BCAAs. With the accumulation of BCAAs in the cell, Lrp responds to BCAAs and binds to PbrnF region and activates the expression of report gene. b The metabolites activate biosensor system to construct the dynamically regulation network, so as to achieve the high-level biosynthesis of value-added compoundsBack to article page
